Running counter which resets after threshold

Hi all,

I'm trying to figure out how to create a counter for how many times a fruit appears, however the count only resets when it appears again after 60 days. I've attached a sample workbook- column F has a running count which resets when the next time that fruit appears is 60 days later, but I cant seem to figure out a formula in column G which isolates that final number for that particular fruit before the counter resets.

Any help would be appreciated!

Thanks
